Electrochemical Grinding: Working, Application, Advantages …

1. Because there is very little abrasive action, Electrochemical grinding does not leave fine scratches which may impair the finish and leave stress raisers.
2. Tolerances of about +0.02 are held on rather complex grinding operations. For closer tolerances, the proportion of material removed by abrasive should be increased.
3. The surface finish is held in the range of 0.2 to 0.4 micron on carbide and 0.4 to 0.8 micron o…

3. The surface finish is held in the range of 0.2 to 0.4 micron on carbide and 0.4 to 0.8 micron on steel.
4. Sharp corners are difficult to obtain and the smallest radius of 0.2 mm cannot be avoided unless a final pass without electrolytic action is used.
